Each numbered component shown in the figure is keyed to the subsequent Table, which identifies the default jumper settings.

2) Board Power

Power-ON LEDs: Initial power testing is performed on the bench using the AC-to-DC power adapter provided in the KCU116 Evaluation Kit.

The status of the Power-ON LEDs is an indication of board health.

a) Check the status of the following LEDs at Power-ON:

b) Ethernet PHY status LEDs.

These LEDs are visible on the left edge of the KCU116 board when it is installed into a PCIe slot in a PC chassis.

The two PHY status LEDs are integrated into the metal frame of the P3 RJ-45 connector, as shown below:

c) Voltage and current monitoring, as well as control of the Maxim Integrated power system is available through either the KCU116 System Controller or via the Maxim Integrated PowerTool software graphical user interface.

The KCU116 System Controller is the simplest and most convenient way to monitor the voltage and current values for the power rails on the board.

A 2-mm JTAG header (J8) is also provided in parallel for access by Xilinx download cables such as the Platform Cable USB II.

a) USB A-to-micro-B cable:

Is the cable visible in Device Manager?
If the three items highlighted in the figure below are visible in Device Manager, this confirms that your USB cable is operational and has been correctly identified.

Check system properties and environment variables.
For information on environment variables, see (Xilinx Answer 11630).

Is the USB port enabled?
You can reboot your system to re-initialize the USB buses.

Are Xilinx tools correctly installed? (Vivado Hardware Manager or ILA)
For supported software version information, see the Kit Product Page:https://www.xilinx.com/products/boards-and-kits/ek-u1-kcu116-g.html
If an issue is suspected with tools installation, see the Installation and Licensing Guide, (UG973) (make sure to use the most recent version of tools and associated documentation which supports the KCU116).

Are cable drivers loaded correctly? Drivers for this cable should be included in the Vivado Design Tools installation.
However, if problems are experienced with the Platform Cable USB II connection, please follow the uninstall and reinstall instructions in (Xilinx Answer 44397).

Check system properties and environment variables.
For information on environment variables, see (Xilinx Answer 11630).

Is the USB port enabled? You can reboot your system to re-initialize the USB buses.

Are Xilinx tools correctly installed? (Hardware Manager or ILA)
For supported software version information, see the Kit Product Page:https://www.xilinx.com/products/boards-and-kits/ek-u1-kcu116-g.html
If an issue is suspected with tools installation, see the Installation and Licensing Guide, UG973 (make sure to use the most recent version of tools and associated documentation which supports the KCU116).

If yes, but Vivado Hardware Manager did not discover and display the JTAG chain, slow down the cable speed (Output > Cable Setup).

If yes, but Vivado Hardware Manager did not discover and display the JTAG chain and slowing the cable speed does not resolve the issue, see the following (assumes Digilent USB A-to-micro B cable is plugged into USB-to-JTAG configuration logic module U21 through J2):

If following the above steps does not allow you to initialize the JTAG chain, please disconnect the Digilent USB A-to-micro-B cable from the board and PC.
Connect the Platform Cable USB to header J8, and connect to your PC.
Ensure Xilinx tools (preferably the latest version of tools that support the KCU116) are correctly installed.
Launch Vivado Hardware Manager - is the cable identified correctly?

If following the above steps does not allow you to initialize the JTAG chain, please review the Support Webpage for your available Support options.

5) JTAG Configuration

If the JTAG chain initializes, but JTAG configuration fails, check the following:

If the above steps fail to enable SPI configuration, please review the Support Webpage for your available Support options.

7) PCIe

If the KCU116 configures correctly, but the PCIe interface does not operate as expected, check the following:

a) Do NOT plug a PC ATX power supply 6-pin connector into J52 on the KCU116 board. The ATX 6-pin connector has a different pinout than J52.
Connecting an ATX 6-pin connector into J52 will damage the KCU116 board and will void the board warranty.
To install and power the board correctly, follow the instructions given in (UG1239) KCU116 Evaluation Board User Guide.

b) Check J7, lane width, is set correctly for your application.

c) See one of the following Answer Records, covering Known Issues for PCI Express, including Kintex UltraScale+:

The Solution Center for PCI Express is available to address all questions related to the Xilinx solutions for PCI Express.

If the above steps fail to resolve the PCIe issue, please review the Support Webpage for your available Support options.

8) IBERT

Note: Running IBERT requires the installation of Vivado ILA.

A device-locked license for this software is provided with the Kintex UltraScale+ KCU116 Evaluation Kit. The KCU116 can run IBERT testing for: FMC, PCIe, and zSFP.

If the KCU116 configures correctly, but IBERT does not operate as expected, check the following:

a) Ensure that all necessary hardware is connected to the KCU116 for IBERT testing.
More information can be found in XTP464 KCU116 Software Install and Board Setup and in XTP459 KCU116 GTY IBERT Design Creation, available on the KCU116 Documentation & Designs tab.

b) Download and run the KCU116 GTY IBERT Design, whichever version is appropriate for your silicon and software version.
It is recommended to always use the latest version of software which supports the KCU116, and associated version of the KCU116 GTY IBERT Example Design.
Follow the associated PDF. All are available from the KCU116 Documentation & Designs tab.

If the above steps fail to resolve the IBERT issue, please review the Support Webpage for your available Support options.

9) DDR4

If a problem is suspected with DDR4 / MIG, check the following:

a) Ensure that the DDR4 DIMM component memory is inserted correctly.

b) Download and run the KCU116 MIG Example Design, whichever version is appropriate for your silicon and software version.
It is recommended to always use the latest version of software which supports the KCU116, and associated version of the KCU116 MIG Example Design.
Follow the associated PDF. All are available from the KCU116 Documentation & Designs tab.

If the issue you are faced with is not listed in the Known Issues and Release Notes Master Answer Record, and the steps above fail to resolve the issue, please review the Support Webpage for your available Support options.
